ebay finds that PWCC engaged in shill bidding?

That was not a theory I posted. I was just asking a rhetorical question, to underscore how it is hard to blame any seller or AH for what may be fraudulent transactions carried out by a card's owner.

That said, especially with extremely rare cards that transact infrequently, an outlier sale can sometimes move the market. If enough buyers, and sometimes it can just be one or two, choose to interpret an outlier as a sign that a heretofore undervalued or under-appreciated card may be getting its time in the sun, the outlier make "take" and affect the next sale.
